FinOps leads
Coverage looks fine at review time. The gap opens after it.
The person who owns coverage, Effective Savings Rate, and the number that goes in the reporting line. A term can end between two reviews, or while you're on leave, and the fleet-wide figure won't say which account is actually leaking.
The person who owns coverage, Effective Savings Rate, and the reporting line above them.
- You report a coverage or Effective Savings Rate number to someone above you
- A term can end between two reviews, or while you're on leave, with nobody else watching it
- You need the number for each account on its own
Where this role gets blindsided
Same role, same three blind spots.
The leak
Coverage measured once a quarter
Between two reviews, instances launch and reservations expire. The number you reported has already drifted by the time anyone checks it again.
What Reserver does
Continuous coverage. Reserver checks coverage every day. Drift shows up on the day it starts.
The leak
A renewal that lands while you're on leave
A calendar reminder only works if the person who set it is watching it. A term ending during a handover reverts to the on-demand rate with nobody noticing.
What Reserver does
A calendar you can hand off. The Expiry Check exports every term to a shareable calendar file with its own reminders, so tracking a renewal doesn't depend on one person's inbox.
The leak
One fleet-wide number, many accounts underneath it
A healthy overall Effective Savings Rate can hide one account carrying the whole fleet and another leaking on its own.
What Reserver does
Filter down to one account. Every scanned instance and reservation carries its account. Filter inventory and reservations to one account to see it on its own.
The fee against the saving
Priced for your fleet size.
A term that lapses between two reviews first shows up as a number you have to explain.
A renewal missed by 14 days runs about $92.
On Watch, catching it costs nothing.
Watch is free, so you keep all of the $10,530 a year.
A renewal missed by 14 days runs about $951.
A single prevented miss pays for about 6 months of Autopilot.
Saves about $105,300 a year. That is 59× Autopilot's fee, which is 2% of the saving.
A renewal missed by 14 days runs about $6,904.
A single prevented miss pays for a year or more of Scale.
Saves about $1,053,000 a year. That is 176× Scale's fee, which is 0.6% of the saving.

Straight answers for finops leads
How is this different from a quarterly spreadsheet review?
A spreadsheet review only shows what's true on the day you run it. Reserver checks coverage every day in between, so you see a slip before the next review.
Can I see Effective Savings Rate as well as coverage?
Not as a live report today. Our guide and free calculator cover the metric. Coverage itself is checked daily and can be filtered to one account.
What if I'm out when a term ends?
The Expiry Check's calendar export carries its own 90/30/7-day reminders, so the date doesn't rely on anyone personally checking a dashboard.
Does this work for one account as well as for many?
Yes. You can filter inventory and reservations to one account, or read the whole fleet at once. Reserver checks each account the same way, every day. The three case studies cover a single startup account and a large multi-account enterprise.
Proof, not a promise
Three accounts, read for your job.
Look for coverage that drifted between reviews. The cards show what each gap cost before anyone saw it.
RDS · ElastiCache · EC2 · 1 account
One missed renewal and one tier never reserved. We priced both.
RDS · ElastiCache · EC2 · 6 regions
Twelve years of careful reviews still missed money between review dates.
RDS · ElastiCache · EC2 · 40 accounts · AWS Organizations
Each account looks fine alone. The loss shows only across all 40.
